An Application Of A Thermodynamic Flow Equation To Water Movement In Unsaturated Soil, Brennan Derry Soane

All Graduate Theses and Dissertations, Spring 1920 to Summer 2023

The movement of water in soil presents many interesting problems to the research worker. It is also a subject which finds wide and important application in agriculture and several branches of engineering.

The object of this work was to examine the usefulness of a new equation of flow of water in unsaturated soil. If valid, this new approach may be able to eliminate some of the gaps in our present knowledge of the subject.

All soil lying above the capillary fringe of a water table is in the unsaturated state with respect to water. This means that in any macroscopic …

The Peltier Effect And Its Use For Measuring Relative Activity Of Soil Water, Hans C. Korven

All Graduate Theses and Dissertations, Spring 1920 to Summer 2023

Soil moisture measurement embraces two basic concepts, namely, water content and relative activity. The measurement of moisture content, either on a weight or volume basis, yields the amount or quantity of water in the soil. The measurement of relative activity or the energy required to remove unit of water is related to the availability of the soil moisture to the plant. The measurement of soil bulk density, irrigation efficiency, and the amount of water to apply in an irrigation are a few examples that require the use of the moisture content concept. Whereas the first concept determines the amount of …

Combining Field Fertilizer Trials With Soil Tests In An Effort To Obtain The Most Suitable Soil Nitrogen And Phosphorous Tests For Southern Alberta, Einard Haniuk

All Graduate Theses and Dissertations, Spring 1920 to Summer 2023

Under dryland farming operations, the use of fertilizers is often restricted due to limited crop response arising from limited seasonal moisture. Once this dryland area is brought under irrigation, there is increased use of fertilizers and increased demands for greater exactness in amounts of fertilizers to apply, due to efforts which are made to increase the returns from the land by introduction of new farming techniques and crops.

On the west side of the valley, the Wellsville Mountain and the southern part of Malad Range have also been studied. Still, little is known about the east-central part of the Malad Range. The study of this area will give additional information to the over-all picture of the geology of the region. The purpose of this thesis is threefold. The first …

The Use Of Branchiostegal Rays To Determine Age Of Lake Trout Salvelinus Namaycush Walbaum, Ross Vivian Bulkley

All Graduate Theses and Dissertations, Spring 1920 to Summer 2023

Any method used in aging fish must fulfill certain requirements to be satisfactory. If the method is inaccurate, naturally little reliance can be placed upon its use. If considerable study of the method and much practice are required before accurate readings can be obtained, the method will not come into widespread use. The requirements of an aging method, then are that it must be accurate and comparatively easy. The scale method for aging lake trout (Salvelinus namaycush Walbaum) unfortunately does not fulfill these requirements. It has always been difficult to tell the age of lake trout by the examination …

Relationship Of Bicarbonate Concentration Of Plant Tissue To That Of The Growth Media As A Factor In Chlorosis, Gary H. Carlsen

All Graduate Theses and Dissertations, Spring 1920 to Summer 2023

Throughout the years lime-induced chlorosis has contributed to untold economic losses. Although this disease has challenged the technical ingenuity of outstanding plant and soil scientists, the exact cause has never been determined; consequently, no preventative measures or permanent cures can, as yet, be recommended. This physiological malady, unchecked, continues its rampage in regions where the disease is prevalent.

The problem is of wide significance because calcareous soils are distributed throughout the world. It is of primary concern to us because the majority of the land of western United States is of this type. An estimated 500,000 acres of crops growing …

Courses For Managerial Training As Recommended By Managers Of Selected Utah Industries, B. Edward Lepper

All Graduate Theses and Dissertations, Spring 1920 to Summer 2023

The United States is a growing nation; it is also an industrial nation. In the past century the spinning wheel has given way to the large clothing mills; a great network of miles and miles of electric power lines has replaced the kerosene lamp and provided power for work that was for years done by hand. Small horse-drawn earth moving equipment has given way to giant motor-driven bulldozers and transportation has progressed from the pony express and stagecoach to the huge trans-ocean airliners that make any spot on the globe only a matter of hours away. In like manner colleges …

A Comparative Analysis Of School Reorganization Of Bear Lake County Idaho, Morris B. Athay

All Graduate Theses and Dissertations, Spring 1920 to Summer 2023

Education, always important, is today more essential than ever if we are to perpetuate and improve our democratic way of life. The recognition of the importance of education in our society has resulted in planning at the national, state and local levels.

Various studies have been made to determine the most desirable type of organization for schools in the United States. One survey made by the World Book Company in Tennessee has given some indication that the size of communities was probably related to educational achievement. The data does not prove any causal relation between educational outcome and community size, …

All Graduate Theses and Dissertations, Spring 1920 to Summer 2023

Many educators consider the shortage of qualified teaching personnel as one of the most serious problems in education. In the past this shortage has been primarily confined to the elementary level. However, the United States Department of Education states:

Long-run forecasts of population indicate that employment of secondary teachers should be higher throughout the forty-year period 1960-2000 than in 1950. The long-range trend for a rising proportion of young people to attend high school is expected to continue. Greatly increased Federal and State aid to education might expand enrollments considerably. The trend toward enriching curriculum, offering special subjects, and extending …

The Effect Of Bicarbonate On The Uptake Of Zinc By Plants, Lawrence G. Morrill

All Graduate Theses and Dissertations, Spring 1920 to Summer 2023

Zinc deficiencies occur in many fruit orchards in Utah even though the soil contains amounts of zinc that would normally be sufficient for good plant growth. The existing zinc problem in Utah is, therefore, one of availability.

Problems of zinc availability generally occur in the pH range of 6-8. Zinc deficiencies occurring within this pH range are more frequently found on well-aerated soils than on poorly aerated ones with other conditions being the same. It has been shown that carbon dioxide will convert both zinc hydroxide and zinc carbonate into more soluble bicarbonates with the concentration of Zn⁺⁺ that …

The impact of this speed has influenced almost every home and certainly every school in America.

The Thermodynamics And Some Practical Aspects Of Zinc Adsorption On Calcite, Dolomite, And Calcian-Magnesite Minerals, Jerome J. Jurinak

All Graduate Theses and Dissertations, Spring 1920 to Summer 2023

Zinc is one of the essential elements required for the normal growth of plants. The total amount of zinc commonly occurring in soils is usually many times greater than that necessary to supply the needs of actively growing plants. The ability of the soil to "fix" zinc in form unavailable for plant use, however, has made the zinc deficiency disease an important plant nutrition problem in the major fruit and nut growing regions of the West. Fixation mechanisms which have been postulated as contributing to zinc deficiency include organic complexes, precipitation of insoluble inorganic salts, and strong zinc-clay intersections. It …

Growth And Nutrition Of Plants As Affected By Different Osmotic Concentrations Of Calcium Chloride And Sodium Chloride In The Substrate, Mumtaz Ali Khan

All Graduate Theses and Dissertations, Spring 1920 to Summer 2023

Considerable experimental evidence supports the concept that the growth of plants generally decreases progressively as the salt concentration of the substrate increases, but certain relationships between plant and substrate are still not fully understood. The chemistry of salt toxicity to plants involves many interactions both as to the quantity and kind of ions presented to the roots and those accumulated in the plants. Many plant species have shown sensitivity to excess accumulation of specific salts frequently encountered in saline soils. Thus Eaton (1942), Wadleigh, Hayward, and Ayers (1951) have shown most of the fruit trees to be susceptible to injury …

Union High School is located in Roosevelt, Utah, on the Uintah and Duchesne county line.

Students come to Union High School from an area of approximately 30 miles radius around Roosevelt. Included in this area is the Ouray and Uintah Indian reservation.

There are approximately 125 full-blood and mixed-blood Indians who should be attending Union High School. The greater majority of these students live on the reservation named above.

Since 1951, when the majority of the Ute Indian students were transferred from the Indian school, there has been a closer association of full-blood Indian, mixed-blood Indian, and white students. With …

A Management Study Of The Cache Elk Herd, Norman V. Hancock

All Graduate Theses and Dissertations, Spring 1920 to Summer 2023

American elk, by virtue of their distribution, were the most cosmopolitan members of the cervid family at the time of white settlement of North America. At this early date elk were present in every major region of what is now continental United States, as well as in northern Mexico. they likewise were abundant in upper and lower Canada, though records do Lot corroborate their presence too far north on the Atlantic coast. Although generally existent throughout the western states, elk were sparsely distributed in Nevada, southern Utah, and most of Arizona and New Mexico. Paucity of elk was also noted …

The Salt Lake Group In Cache Valley, Utah And Idaho, Robert D. Adamson

All Graduate Theses and Dissertations, Spring 1920 to Summer 2023

Fluvial and lacustrine sediments of great thickness accumulated in the intermountain basins of the western United States during Tertiary time. The Salt Lake group in northern Utah and parts of surrounding states is a conspicuous stratigraphic unit of these basins. The "beds of light color" in Morgan Valley in the Wasatch Mountains of northern Utah were named the "Salt Lake group" by Hayden (1869) because of similar occurrences in Salt Lake Valley and because he reasoned that the succession could be divided into formations. Similar rocks crop out in Ogden Valley, north of Morgan Valley, and in Cache Valley, Utah …

A Study Of Instructional Practices And Recommendations Of Thirty-Five Successful Biological Science Teachers In The Secondary Schools Of Utah, Gerald H. Raat Jr.

All Graduate Theses and Dissertations, Spring 1920 to Summer 2023

This study is concerned with the teaching of biology in Utah secondary schools. It is based chiefly on analysis of: (1) the teaching procedures used by thirty-five teachers of biology in Utah who were designated by their principals as being outstanding teachers, and (2) the facilities and equipment these teachers think are essential.

As long as schools exist there will be need for studies concerning teaching methods, facilities, and equipment. Man's ever-widening knowledge about science and the wide range in abilities of pupils in our schools make such studies in science particularly important. Perhaps the following will serve to emphasize …

Comparison Of The Utah State Agricultural College Mathematics Entrance Examination Computational Form Versus Multiple-Choice, Wilson Walker

All Graduate Theses and Dissertations, Spring 1920 to Summer 2023

It is the standard practice in colleges and universities to administer to all entering students a battery of tests which are designed to measure the aptitude and ability of students. Each institution uses in its test battery those tests which are best suited to its particular needs, but in the main they consist of measures of general mental ability, the ability to understand and use the English language and the ability to understand and to use mathematical symbols. These tests are available to the institution through companies which construct and standardize tests of all kinds. In addition to these tests, …

The Influence Of Soil Moisture Conditions On The Absorption Of Phosphorus By Plants From Calcareous Soils, T. J. Denman

All Graduate Theses and Dissertations, Spring 1920 to Summer 2023

Phosphorus is one of the major plant nutrients secured from the soil. The object of many investigations has been to discover the nature of the processes by which the soil supplies phosphorus to plants, and to determine the influence of soil factors upon these processes. Although much knowledge has been gained, these processes and the effects of soil factors upon them are still not clearly defined.

One factor which profoundly affects plant growth is the amount and relative availability of soil moisture. The results of some investigations have suggested that this factor may also have considerable influence on the absorption …

The Content Of Essential Amino Acids In 1950 Alfalfa Hay Grown In Utah Soil Treated With Different Fertilizers, Adriana Lanting Kunkel

All Graduate Theses and Dissertations, Spring 1920 to Summer 2023

Application of fertilizers to soils to increase production yields has raised questions concerning the effect of fertilizer on chemical composition of plants. With the development of accurate, sensitive microbiological methods for the determination of amino acid in protein, speculations concerning amino acid content have been supplanted by acquisition of facts.

The effect of the different fertilizer applications on alfalfa yield has been discussed by Jones, et al (5). Also, some work has been done to determine the effect different fertilizers might have on the amino acid content of plant material. Some values (1,3,12) have been reported for the amino acid …

Soil Additives And Their Effect On The Yield Of Various Crops And The Physical Properties Of An Agricultural Soil, Gaylen L. Ashcroft

All Graduate Theses and Dissertations, Spring 1920 to Summer 2023

It is generally accepted that soil structure is very important in keeping productivity at a high level. When soils are loose and friable, mechanical impedance to root growth and seedling emergence is greatly reduced. Such soils infiltrate greater quantities of precipitation, are better aerated, and possess a more favorable temperature than puddled soils. Essential plant nutrients are also more easily available in well aggregated soil.

In the last few years, several synthetic soil additives have been placed on the market. Extravagant claims have been made about the ability of these amendments to maintain soil structure, without a sound body of …
